TBI 24 pin IC -> Flash 28 pin IC
Hey guys!
I'm certain that this has been covered a number of times in the past, but doing searching has only turned up replies to buy a G2.
However, I'm under a bit of a time constraint, and don't have the time to order one up, so I need to rig things up myself.
I've got a spare low profile 28 pin ZIF to install, but I need to know what I should be doing with the left over pins, since the TBI only uses the first 24.
Do I just remove the pins from the ZIF, or do I need to ground them / hook them to another pin?
Also, what offset do I need to be programming to on my 27SF512 chips?
Thanks!
Russ

I made one myself before the G2 became available. I used pins from an old IDE connector, a project PCB, and a ZIF and soldered it in. Its certainly doable if you have the pinouts of each chip, but itll be alot easier to just order the G2. If you order now, you could probably get it by the end of the week.
If your really intent on doing it yourself, go to radioshack and pick up a project board (I forget the correct pin spacing), some hookup wire, solder, etc. and download the datasheets for the 27SF512 and 2732.

I second dimented, just order from moates, the g2 adapter works great. I just installed one in an 8746 ecm and with a little soldering skills you'll be in much better shape. Unless you're really adept in electronics you can create lots of headaches.

Well, I found a 350 prom to use for now, and it appears that the truck runs on it actually really well. Need some work in the upper VE tables, but the bottom end looks fantastic.
I'll order up a G2, and get her rigged up that way instead, as it is very driveable to make it to the lake this weekend
